IMPROVEMENT IN BooTs AND SHOES.

The Schedule referred to in these Letters Patent and making part 0f the same.

I, LEVI H. WHITNEY, of Washington, in the District of Columbia, have .invented a certain Improvement in Boots and Shoes, of which the following is a specification, reference being had to the annexed drawing making part of this specification, and in whichf Figure 1 is a bottom view of a boot or shoe embodying my improvement.

Figure 2 is a section thereof.

The same letters are used in both gurcs to designate identical part-s. l

This invention relates to the manufacture of boots and shoes; and Y My improvement consists in arming the heels and soles thereof with hardened-steel screws, for the p urpose of preventing their rapid wea r,'as will be more fully desvribed hereinafter.

Various attempts have been made to arm the heels and soles of boots and shoes in such a manner that they might last without needing repair until the uppers were used up, but there was always some'objectionable feature connected with suclran armature.

Metallic plates, for instance, have been attached to them, which were objectionable on account of ltheir cost, and, more particularly, because` they deprived the boot or shoe of its elasticity, which is so desirable.

Again, nails have 'been used, which, in order to dinarily.

havesthem take a good hold, had to be driven in so Y far that, as the heads wore ofi', they would be pushed entirely through the soles, and injure the, feet of the wearer of the boot or shoe.

Iv have endeavoredto overcome atl objections to such au armature by using for-that purpose short gimlet-pointed screws, A, made of steel and hardened to any desirable degree. v

They are applied substantially in the manner shown in the drawing, by countersinking their heads in the soles, so as to make them flush with the under surface thereof. f Their length depends upon the thickness of the soles; beyond the outer one they should not pass or- What I claim as new, and desire to secure by Letters Patent, is-

A bootor shoe, the sole, or sole andi heel of which are armed with hardened-steel screws, substantially in the manner and for the purpose set forth.

In testimony whereotl I have h signed my name to the above specification in the presence of two wity nesses.
